. Application filed January 29, 1924. ySeratNo. 689,228..

This invention relates to a container or can and the object is to provide a container inwhich the top jlmay he sealed with any es` p'ecially `tight seal to prevent gases from y leaking into or out of the container fromv I which the top may easily be removed when` y Vfit' is. desired to fopen the container.

'Y ,y i Another objecty of the invention is to prof vide `an easily opened container .which has 410 an especially strong endl so constructed that veven though the container may easily be opened whenfproperly manipulated it will standr extremely rough usage incident to packing, shipping, etc., without opening or 15 breaking'the seal.

i. further object i ofv the invention is to Aprovide acontainer which may easily, quickvly land cheaply be manufactured.

i, Other objects and features of the inveny tion will' more yfully appearfrom the following 4description and `the accompanying drawingsv andv will beV particularly pointed out Yin the claim. n

i In the drawings:

',25 Fig. 1 is a section` through'one endof a held on the body v,of vthe container. by having the end of thefbodyand the edge of the closure rolled andlfolded to forma seam. This seam when properly made joins the can l notlbe separated without destroying either f Athe bodyor the end. It sometimes happens that in forming this seam the edge of the `closure body or the edge of the flange on the cl'osu-rcis slit, or `the flange or the end l iofthe body is wrinkledduring the folding process with thevresult *thatv .air may Vleak into the canorQ the rgases in the can may 4leak:through `the seam4 into theatmosphere,

l within' they container. Y ,Y Y y With the container of the presentA invention, however, the body of the container `i. and 4the' closurexth-erefor are'formed sepa-` f y' ,.rately. so that .any imperfection occurringA end to the body so securely that they can out of thecontainer. L l

during the forming of' thesel parts can` be noted, and the" container .is assembled ,fromv the pre-formed kparts in suchmannerythatf s permit `the vcome the parts are put under nest-rain and have no tendency to breakor .pleted container to leak.

Another feature o fact that with a' container constructed in accordance with Lthe present invention Ithere f. the invention is the 1 are` a number of recessesor'places/where i.

a sealing materialmay lieto v'provider a tight juncturebetween theV body and closure of *i the contain/erf A lfurther feature 'ofl the inventionf'lis the fact `that even though the closure. for the container is-tightly and securely Vheld on lthe body thereof, the container" may easily be i i opened when struck in theproper ,manner but will irmly 'resist any'opening operations which are performed thereon in an improper manner. o

The container illustrated in Fie. tremely simple construction. In i'his gure', l

`designates thelowerportion ofthe body of 1 isi-ofeX- the container and 2 designatesthe upper por- Otion of the body which lis inline with the f I lower portion. The end 3 of the body ofthe container ishent at 4 so thatsaid end lies parallel with but spacedfroin. the upper 'por-k vtion 2 of thcbody. The closure. for the'con' tainer consistsofa central portion 5 and av rim which comprises an inner. flange-6 and ,an outer flange 7 which maybe, andy prefer`.

ably are,'integral withLthe Vcentral portion `90 i of the closure,.'.l `he innerand/ outer flanges i .are connectedby the bend 8 and `spaced .from` one anothertofreceive the endl 3-of the body, `andthe rinitis connected to'fthe central-portion'. ofltheclosure vby the bend 9. Thus a recess 10l ispro-vided in thebody .ofthe container to receive a sealing material andanother recess 1l is` provided inthe closure forlikeupurposes and whenthe parts are vin the position shown in Fig@ 1 there are-two sealing recesses in the juncturebetween Athe-closure andthe body of the container whichv recesses when .filled "with the sealing material. form ay seal which. eec` ftively preventsl any passageof gas inttoor The formation of thej inner and-.outer flanges vto provide thewrecess 11causes-the' central portion ofthe closure-telo@ rS0 posi- ,tioned that -itfforrns a 'panel in,y the end of rvthe container which lies more or less-,onf the level ofthe ektremefjend ofthe contanerdeeoy pending upon the length of the iange 6 and the desired depth of the recess 11. :in the container illustrated the' central portion or panel of the closure is on the level with the bend 4 of the body thus providing the deep recess 11 and also giving the end of the can a finished appearance. With the panel of the closure as shown in the drawings the end of the container is practically smooth and eX- cept for the small crevice at the juncture of the panel and bend t of the body there is no place for the lodgment of dust which collects on the top of the usual containers when they are stacked on shelves or otherwise stored awaiting shipment and sale. It is to be understood. however, that the invention disclosed in this 'application is not to be limited to a container having the panel. on vthe level of the extreme end ofthe container as, if the feature of having the end of the container dust proof is not desired, the panel maybe lowered as much as desired to provide the recess 11.

The closure is held within the container by the frictional engagement of the outer fiange -6 with the upper portion 2 and the end 8 of the body and also by the frictional engagement of the end of the body with the fianges. In order vto more securely hold the closure in the end of the container the body may be provided witha projection 12 which extends within the container under the bend 8 and contacts with the shoulder 18 formed by the bend. Although the projection may have any forni it is preferably a continuous beading formed after the closure has been placed in the end of the container at the same time that the flanges and end of the body are pressed together to ysecure the closure to the body of the container. Although the projection extendsinwardly sufficiently to prevent the closure from dropping down into the container away from the body end, it is yet so resilient that it permits the closure to slip away from the end of the container when pressure ris lapplied to the closure at its periphery. The projectionthus assists the flange in holding the closure in the open end of the container but still 'permits the closure to be forced away from the flange when it is desired to open the containeizu ln opening the container the closure is struck by a series of light blows progressively around its periphery. These blows break the sealing material and force the closure downwardly away from the end of the body and the closure may then be drawn through. the opening end of the container so thatthe contents of the container may be emptied.

The container illustrated is made by providing the body without the projection 12 and then turningthe end of the body inward parallel with the main portion thereof but spaced therefrom toform the recess 10. The closure may bemade by stamping the panel and inner downwardly extending flange from a sheet of the desired metal, preferably tin, and then turning the edge of this flange in an outward and upwardfdirection until it lies parallel with the inner fiange to form theouter flange and the recess 11.

After the body and closure are formed rnaferial is placed in the several recesses. Although various kinds of sealing material may be used the preferred material is a liquid which is quite fluid as placed in the re# cesses but which becomes viscous as it is exposed to the air and dries until when thoroughly dry it is an elastic solid. The closure and body arepermitted to stand until thc sealing material is dry at which time the container may be assembled by inserting the closure through the end of the container not shown on the drawings, and pushing it through the container until the flanges and body end are properly seated in the recesses and interlock in the position shown in the j drawings. In order that the parts may inH terloch properly but still permit the closure easily and freely to be moved through the body of the container, it is necessary that the diameter of the closure be just the same as the internal diameter of the container.

As the flanges on the closure and the end of the body are forced intoengagement the sealing compound is pressed between the contacting surfaces to give an exceptionally tight seal. the body the container is placed in a can machine which presses the upper portion 2 of the body and the inner flangeG toward each other to join the closure to the body. rl`he machine comprises the chuck 14; which extends up in the container to bear against the inner flange 6 of the closure, and the roll which bears with great force against the upper portion 2 of the body to squeeze thc. rim 4of the container into a rigid, tight# ly sealed structure. lf the beading 0r projection 12 is desired a roll is used which has the boss 16 on it toforrnthe beading and press it into the desired shape contacting with the shoulder 13. i

The container shown in Fig. 2 is made in practically the saine way as is thecontainer shown in Fig. 1. In the container shown in Fig` 2, however, the outer flange 7 of the closure is folded upon itself at 17 to pro With the closure in the end of vide a rim which is stronger and more rigid than the rim of the container shown in F ig.

l but yet provide a container which will open easily and without the use of a can opener orrother special tool.

The container shown in Fig. 3 is as strong A container of the forni shown in Fig. et

has an exceptionally strong and rigid rim i and is Very tightly sealed but may beiopened with ease. Both the end of the body and the outer' flange of the containerare folded -upon'themselves thusgiving a rim for the lcontainer which contains siX thicknesses Y of metal. yTherecesses 10 and 11 are of Lto openitif the effortsare not properlyvdi-y rected. vTo open the container it is necessary' double width ,and ythus hold a large quantity 1 of they sealing material. Vith a container having'a rim oftliis type there 'are two open spaces 19 and 20 left entirely around and ,wfithinvthe` container rim.- The sealing'rna-` terial collects'pin these spaces -as the`container is being made and forms two sealing rings or gaskets within the contaner rim and through which gas or` any of the contents of' the container must pass before they can leak from the container.

' to tap the closure progressively around the periphery at or near the bend 9,. If' the blows are delivered at the periphery', the rim of the closure receives a large component lof the force of each blow and the rim is gradually driven downward away from the end of thebody until the closure is entirely free. ,If the. closure is struck at or near the center of the panel, however, avery small componentof the force of the 'blow is effective at the rim of the closure to drive the rim downward, the majority of the force of `the centrally delivered yblow tending to pull the rim of the closure 'towardthe center of 'the container. Thisytendency is stoutly` re- `the rim of the container.

sisted, however, by therigidity of the vcombined flanges and body which together form Thus the container describedherein is tight and strong name to this specification.

and will notvopen unless the closure is prop#` l erly struck, but if it is manipulated in the manner above setforth the container opens quite readily Withoutthe use ofa special tool for in anyway cutting or tearingthe' closure away from thebody. 'y
